Hi,
you can do it via programing just user these class libraries of dnn to create new user(s)
just make a userinfo class object and set the required value to it like given below:
Dim ObjUserInfo As New DotNetNuke.Entities.Users.UserInfo()
ObjUserInfo.Username = TxtUserName.Text
ObjUserInfo.FirstName = TxtFirstName.Text
ObjUserInfo.LastName = TxtLastName.Text
ObjUserInfo.IsSuperUser = False
ObjUserInfo.Email = TxtEmailAddress.Text
ObjUserInfo.PortalID = 0
ObjUserInfo.DisplayName = TxtDisplayName.Text
ObjUserInfo.Membership.Password = TxtPassword.Text
ObjUserInfo.Membership.UpdatePassword = False
'' Then pass it to the below Dnn Method
Dim createStatus As DotNetNuke.Security.Membership.UserCreateStatus = DotNetNuke.Entities.Users.UserController.CreateUser(ObjUserInfo)
''createStatus will show the output whether user has been created or not. which you can display in Label
I hope this would help you :-)
